This function uses the L3-02 value to limit the output current and automatically adjusts the acceleration rate.
When the load (output current) increases to more than the current limit level during acceleration, the drive
automatically adjusts the acceleration rate.

Name Description
Default
(Range)
L3-02
(0490)
StallP Level@Accel
Sets the output current level at which the Stall Prevention function operates during acceleration
where the drive rated output current is 100%.
Determined by C6-01 and
L8-38
(0 - 150%)
Note:
• If you use a motor that is small compared to the drive and the motor stalls, decrease the setting value.
• When you operate the motor in the constant power range, set L3-03 [StallP Limit@Accel].
• The upper limit to the setting range changes when the setting for C6-01 [ND/HD Duty Selection] changes.
– 150% when C6-01 = 0 [HD Rating]
– 120% when C6-01 = 1 [ND Rating]
■ L3-03: StallP Limit@Accel
No.
(Hex.)
Name Description
Default
(Range)
L3-03
(0491)
StallP Limit@Accel
Sets the lower limit for the stall prevention level used in the constant output range as a percentage
of the drive rated output current.
50%
(0 - 100%)
The stall prevention level set in L3-02 [StallP Level@Accel] is automatically reduced when the motor is running
within the constant output range. Parameter L3-03 is the limit value used to prevent the stall prevention level
during constant output ranges to fall below the minimum required level.
Note:
The function to automatically reduce the stall prevention level does not operate when L3-01 = 4 [StallP Mode@Accel = ILim Mode].
